All of the above and then some. I've had them since I was 9. My doctor told me upfront that they get worse during pregnancy from the increased blood volume. They're not dangerous unless you're going into ventricular tachycardia or a-fin. Ask for an EKG if you're worried about it but I'd assume you're fine.

I have them on and off for years, and finally in the last 2 weeks they were bothering me to the point I'd get them laying in bed and even get out of breath. I asked my doc about it and she said it could easily be a combination of dehydration, low zinc, and low electrolytes. (Granted I have no diagnosed heart murmur or other arrhythmia) so I started taking more zinc added, another 20 oz of water and took EmergenC to balance electrolytes for 6-ish days and haven't had a problem since... unless I forget to take zinc, drink water or EmergenC! Just a thought!

what did the cardiologist say? Mine gave me a whole "It's probably just pregnancy" speech until they actually did an EKG and I failed due to some abnormalities. It prompted an echocardiogram and an annoying heart monitor, but at least we know and have a plan for childbirth now, which was essential in my case.

That's great! I still know plenty of people who check out okay on their EKG and have very annoying symptoms. Sorry you are dealing with that :( I have a mitral valve prolapse, severe sinus tachycardia and "significantly reduced heart rate variability for my age". MVP is very common but I happen to have a good amount of regurgitation with mine, which is causing all sorts of issues. I had always felt the issues pre-pregnancy but it was only while I was at the gym, stressed or oddly - sleeping (it would wake me in the middle of the night). I got it checked out when my shortness of breath and chest pains seemed significantly beyond a simple pregnancy annoyance. Good luck with your symptoms!!

I'm on a beta blocker, Propronolol, which is the only one my cardiologist feels comfortbale with. He'll make the call in conjunction with my OB on May 2 whether I will go the c-section route or do a medicated vaginal delivery. My OB threatened to cut me off if I wanted to try play the unmedicated card on her :) Apparently having an epidural will decrease the stress on the heart.

Yes I got these regularly and it's stressful and annoying. Had echo and stress test and everything is normal. Doctors say not to worry but I'd really rather if they weren't there at all! It's only started in the last year. I have no idea what's the cause but I find if I eat well and walk regularly they sometimes go away. Look into magnesium supplements aswell. It's almost the first thing a cardiologist will put you on.

That's what I'm hoping. The most VT I've ever had was six consecutive beats after seven mins of sustained SVT at 280. Even then, the electrophysiologist said that amount of VT was "completely normal". He told me I'm on of the unlucky few who is able to feel every heartbeat, normal and abnormal.

How severe is your sinus tachycardia? My EP took me off beta blockers as soon as I found out I was pregnant. My average without meds is right around 100. I loved being on beta blockers, though. 60-70 bpm gave me peace of mind.
